perl-depends - Roughly find out module depends from Perl file(s) SYNOPSIS
perl-depends [options] FILE [FILE ...] DESCRIPTION
Find out roughly the modules the program uses. This is based on the idea, that Perl evaluates the "use" commands at compile time and stores the loaded module information into the %INC variable. By examining the loaded modules and comparing them against the standard Perl modules, the external module dependencies can be roughly estimated. The depends information can be used to determine what external modules have to be installed before a program can be used. The target FILE have to be instrumented with the dependency checking code. The resulting "binary" is then stored in a temporary file which the user runs. This program does not run the instrumented files because it cannot know what possible options need to be passed for the program to trigger "no behavior". That is, something that doesn't actually involve executing the "binary" in real. Such options passed would include --version, --dry-run, invalid options like --generate-syntax-error-now, or invalid files etc. to make program stop on error. The user can know better the details of running the intrumented file. An example of output: the external module depends here is 'Regexp::Common' and the rest of them can be ignored. Regexp::Common Regexp/Common.pm Regexp::Common::CC Regexp/Common/CC.pm ... OPTIONS
-e, --extension=EXT Use extension EXT for instrumented files. The default is ".tmp". -h, --help Print text help --help-html Print help in HTML format. --help-man Print help in manual page man(1) format. -v, --verbose LEVEL Print informational messages. Increase numeric LEVEL for more verbosity. -V, --version Print contact and version information. EXAMPLES
Instrument a file, run it to see results and delete instrumentation: perl-depends file.pl perl file.pl.tmp --version rm *.tmp TROUBLESHOOTING
None. ENVIRONMENT
None. FILES
None. EXIT STATUS
This program's exit status is not defined. The instrumented programs exit status is 1 in case external moduels are displayed and 0 if no external modules are found. DEPENDENCIES
Uses standard Perl modules. BUGS AND LIMITATIONS
